SPECIFICATION forming part of Letters Patent No. 696,010, dated March 25, 1902. Application filed December 3l, 1901` Serial No. 87,884. (No model.)

To all whom it mfr/7j concern,.-

Be it known that I, FRANZ DAHL, a citizen of Germany, and a resident of Bruckhausen, Rhineland, Germany, have invented certain new and useful Improvements in Hydraulic Presses, of which the following is aspeciiication.

This invention relates to an improved hydraulic press or similar machine, and more particularly to improved means :for lifting the Work ott the matrix in a simple manner.

In the accompanying drawing-s, Figure l is a longitudinal vertical section of the lower portion of a press embodying my improve` ment. Fig. 2 is a plan. Figs. 3, 4, and 5 are vertical cross-sections of the press, showing consecutive positions of the parts; and Fig. b', a Vertical cross-section of a modication.

The letter c represents the matrix of a hydraulic or other press by Which the Workpiece A is stamped. The matrix is slotted near each end for the accommodation of a pair of transverselevers h. These levers have a vertical and also a tilting motion. They are provided at their pivoted end with an elongated opening or slot b', that receives the pivot 7i, such pivot being of a diameter less than the major diameter of the slot. The levers l) rest on a longitudinal beam a, engaged by a plunger d, that Works Within a chamber of the plate e.

In use the plunger d is raised to rst raise and then tilt the levers h. The raising of the levers Will cause them to rst engage the Work-piece A, Fig. 3, and to then lift it vertically above the matrix, Fig. 4. The tilting of the levers d will throw the raised Workpiece ed the matrix, Fig. 5.

In Fig. 6 the pivot 7i of the lever b is Vertically movable to permit the vertical movement of the lever, While the elongated slots ZJ are dispensed With.

W`hat I claim is- 1. In a press, the combination of a matrix, with levers adapted to engage the Work-piece, and with means for imparting successively a Vertical and a tilting movement 1:0 the levers, substantially as specified.

2. In a press, the combination of a matrix, with levers engaging the Work-piece and movable vertically at their pivoted end, a beam engaging the levers, and a plunger engaging the beam, substantially as specified.

Signed by me at Dusseldorf, Germany, this 17th day of December, 1901.
